JAMES-H. MARTIN, OF FALUN, KANSAS RAIL-HJOINT.

Specification of Letters Patent.

Patented April 9, 1907'.

Application filed January 9, 1907. Serial No 351,549.

To aill fwhomit may concern.-

' her 7 is comparatively thick with relation to Beknown th JAMES MARTIN,a I the inner 1nen1ber 6 and has its outermost citizen of the UnitedStates, residing at-Fawall extending solidly in a diagonal plane Inn, inthe county of Saline and State of from the outcrlowcr corner of the headof the Kansas, have invented certain new and use- 'f'ul Improvementsiii-Rail-Joints, of which the following is a specification.

3 The object of my invention is to provide a very simple, inexpensive,and efficient form of rail-Iioint which may be readily applied to therai s that have already been formed without the necessity of remoldingthe rails The invention consists in certain construc tions andarrangements of the parts hereinafter full described-and claimed.

For a description of the invention and the merits thereof and also toacquire aknowledgeof the details of construction of the means foreffecting the result reference is to be had to the following descriptionand ac- Figure 1 1s a perspective view illustrating the application ofmy improved-rail-joint. Fig. 2 is a horizontal sectional view thereof.Fig. 3 is a detail view of the chair, and Fig. 4

is a transversesectional view.

i Corres onding and like parts are referred to in the. ollo'windescription and-indicated. in all the views 0 the drawings by the samereference characters.

Referring to the drawings, the numerals -,1 and 2designate the meetingends of two rails, each of which is sawed alon a strai htdiagonal lineto form the straight scar -joint or edge 3, which extends entirelythrough the tread portion and web and base of the rail along'the sameplane,'so that the said 'edge' or jolntmay. be formed by merely sawing arail that has alreadybeen formed and without the necessity of remoldingthe rail.

I 4 designates my improved chair, which is constructed of one integralformation, witha base '5, e"xtending underneath the base of the twoadjoining rails and with an inner member fi and an outer-member 7. Theinner member 6 extends over the inner base-flan e of the-rails atthe'joint thereof and tight y hugs the adjacent side wall of the web andI eiitendsup under the head of the rail and is of such thicknessthat itsoutermost side extendsfiush with the side edge of the rail at the headthereof, as shown. The outer member 7also extends over the opposite baseflange andclosely hugs the outer wall of the web and the lower wall ofthe head, and it is rail to the base 5 of the chair. Thus the chair isformed with one comparatively thick member at the 'outenside of therails and a thinner member at the inner side thereof, the

1 strain being greater at the outside than at the inner side.

8 designates bolts which extend entirely through the fish-platesconstituted l the members 6 and 7 of the chair and am through the websof the rails, said webs being slotted, as indicated in Fig. 2, to allowfor expansion and contraction. By the construction of the scarf-joint asherein described not only may the meeting ends of the rails be sawedinto the desired shape, but the wheels of the cars will in travelingover the joint always tread upon a solid portion of the rails, andthereby avoid the wearand jar which the meeting ed es are at rightangles to the length of the rails.

As shown best in Figs. 3 and 4, the chair 4 is provided with an larrecesses 4 to receive the nuts of the olts 8, so that the same may lisquare on the bolts, as shown. Within each one of these. recesses. is anopemng which extends-into the chair and is adapted to receive alocking-pin 4*, so as to prevent the nut from -turning after it has oncebeen screwed up. 1

From the foregoing description, in connection with the accompanyingdrawings, it will be. seen that I have provided a ve simple, durable,and inexpensive form of rail-j oint of the character described.

' Having thus described the invention, what is claime as new is 1. Thecombination with the ,meeti I ends of rails that are'formed with adiagona edge that are-incident to the joints of rails ining the webthereof and the under si e of the adjacent portion of the head of therails, such inner member being of a thickness thatits exposed wall liesflush with the side edge of tobe particularly noted that the outermemthe head and extends downwardly in a vertical plane therefrom, andthe outer member of said chairexte nding over the opposite basefiange ofthe rails and snugly engaging the adjacent wall of the web and theunderneath portion of the head, said'last-named member of thechair beingcomparatively thick with respect to the other member and having itsexposed wall extending. in a diagonal plane from the outer side edge ofthe head of the rail down to the base of the chair, and bolts extendingthrough the two members of the chair and through the webs of the rails.v

' 2. The combination with the meeting ends ,of mile the webs of whichare provided with slots, of a chair adapted to extend under seaeoe"eitend up alongside of the rails, one member of said chair beingprovided with angular recesses 4* and with openings in said recesses,both members of the chair being formed with boltholes and boltsextending through said bolt-holes and through the slots of thevWebs] Iand provided with nuts fitting within the angular recesses of the chair,and locking-pins inserted in the said openings and adapted'to lieagainst the nuts, as and for the purpose set forth.

In testimony whereof I afiixmy signature in presence of two witnesses. 7
